Front Tracking Based Numerical Investigation of Relations Between Columnar Dendrites Permeability and Macrosegregation Evolution
Mirosław Seredyński , Jerzy Banaszek
AbstractNumerical simulation of binary alloy solidification process is a challenging task due to coexistence of phenomena related to various temporal∕spatial scales and coexistence of zones, i.e. columnar and equiaxed dendrites, where various fluid flow models should be applied. Presented paper is devoted to exploration of the recently developed numerical model of solidification based on the front tracking approach. The influence of the columnar dendrites region porosity on the macrosegregation formation is investigated. Presented results stay in qualitative agreement with the reference data but expose some additional details absent in the results of simulation performed with the simpler model.
